Abstract
Polymers including α-hydroxymethylacrylate units and methods of preparing polymers from α-hydroxymethylacrylates are provided. Advantageously, α-hydroxymethylacrylates may be used in an emulsion polymerization and function as a polymerizable surfactant. The ability of the α-hydroxymethylacrylates to be used as a polymerizable surfactant allows for emulsion polymerization systems to be prepared without other surfactants.
Claims16
A method of preparing a polymer comprising:
- an emulsion polymerization that employs at least one α-hydroxymethylacrylate as a reactive surfactant and does not employ an additional surfactant other than the at least one α-hydroxymethylacrylate,
- where the at least one α-hydroxymethylacrylate is defined by the formula:
- where R2 is a hydrocarbon group with at least 3 carbon atoms.
A latex comprising:
- a polymer with units derived from the emulsion polymerization of at least one α-hydroxymethylacrylate employed as a reactive surfactant, where no additional surfactant other than the at least one α-hydroxymethylacrylate is employed;
- where the at least one α-hydroxymethylacrylate is defined by the formula:
- where R2 is a hydrocarbon group with at least 3 carbon atoms.
